A circular metal loop whose radius is 6:0 cm carries a current of 5:0 A. It is horizontal, while the earth's field points North and 60? below the horizontal. (The earth's field has a magnitude of about 0:50 Gauss, which is 0:5 10?4 T.

a) If the current flows clockwise as viewed from above, then what is the magnitude and direction of the magnetic moment vector?
b) What is the torque on the loop due to the earth's B-field?
c) The loop would have the least possible energy if its magnetic moment were parallel to the B-eld.

How much work is needed to move it from this parallel position to the horizontal position described at the start?
